"We have taken the unusual step of releasing the images - which carries a warning for viewers - in the hope that someone will recognise the car and come forward with information so that we can trace the driver."

Doctors at the city's Coventry and Warwickshire University Hospital confirmed the pair only suffered minor injuries during the crash, but Jones said it could have been "so much worse".

"At the time of the collision, the driver would not have known that the woman and child were uninjured," she added.

Anyone with information on the movements of the car before or after the collision should call PC Jones on 101. Alternatively, people who do not want to speak with police officers can call Crimestoppers anonymously on 0800 555 111.
